AMR Success From Coast to Coast

Although climates may differ and habits may vary widely, communities along the Pacific and Atlantic Seaboard have one thing in common: a need to conserve and protect their water resources.

In Ann Arbor, MI, that commitment has resulted in the city receiving the Ten Years of Excellence award from Metering/Billing CIS America, being honored for an “innovative implementation of advanced metering technologies by a water utility in North America.” Because Ann Arbor is home to the University of Michigan, meter responsibility often changes hands as a result of the transient student population. By using C700 positive displacement meters by Elster AMCO Water, the city can avoid physical disconnection and reconnection when the meters switch to new occupants, saving time and money.

As a long-term municipal customer of Aclara—and a user of the STAR Network system—Ann Arbor has experienced great success in the deployment of advanced metering infrastructure designed to collect water usage data that can be used to track water usage and provide customers with daily consumption information. The data is also used for Ann Arbor’s tiered-rate billing system (for both commercial and residential customers) that bills customers based on usage.

On the other side of the country, the City of Spokane, WA found the perfect solution to a sticky security situation by switching the local airport’s water meters to Itron’s Water Fixed Network technology. In the past, meter-reading employs were forced to navigate the airports multiple security gates to access water meters, which were placed through the airport property. Complicating matters was that the sparsely populated area surrounding the area required an additional two days of meter reading. The city eventually agreed to deploy 200 Itron meters in a 10-square mile area in and around the airport.

As a result of this new metering system, meters are now read offsite, and monthly billing more closely corresponds with the periods of usage. Spokane has also discovered that its new AMR system helps with leak detection and has inspired its commercial customers at the airport to keep a closer track of water usage.
